Floating type inflation head device

Abstract

The utility model discloses a floating type inflation head device which comprises a mounting seat and a plurality of adjusting mechanisms which are uniformly arranged along the periphery of the mounting seat, a through hole for the inflation head to penetrate through is formed in the mounting seat, and a jacking rod of the adjusting mechanism extends into the through hole to jack the outer wall of the inflation head; the diameter of the through hole is larger than that of the inflation head. When the inflation head is in butt joint with the filling port, the inflation head jacks the jacking rods of the adjusting mechanism, so that the corresponding jacking rods stretch out or retract, and self-adjustment of the position and the angle of the inflation head is achieved. When the inflation head is in butt joint with the filling port, if the position between the inflation head and the filling port deviates, the inflation head can abut against the jacking rod of the adjusting mechanism, the jacking rod moves or rotates in the through hole, and therefore the inflation head can be automatically adjusted to be in butt joint with the filling port accurately. In the process, rigid collision cannot be generated between the inflation head and the filling port, the situation that the filling port is damaged is avoided, and the safety of the filling port is protected.

Description

Technical Field

[0001] The utility model relates to an inflation device, in particular to a floating inflation head device. Background Art

[0002] Currently, in the field of plastic hollow cavity processing, due to certain dimensional fluctuations during the molding and subsequent processing, even certain relatively precise parts, such as the cavity's filling port, still experience an error of approximately +-3mm. After the cavity is processed and assembled, it is necessary to conduct a leak test through the filling port. However, due to the +-3mm error in the filling port, when the existing automated inflation device is connected to the filling port, the inflation head of the inflation device may cause a rigid collision with the filling port, resulting in irreversible damage to the filling port and causing the product to be scrapped.

[0003] Therefore, it is necessary to design an inflation head device that can ensure that the inflation head is smoothly inserted into the filling port without damaging the filling port. Utility Model Content

[0004] The present invention aims to address the aforementioned issues by providing a floating inflator head device with a simple structure, self-adjustment, and high adaptability. When the inflator head is docked with the filling port, the inflator head device can adaptively adjust the inflator head, enabling accurate docking without rigid collision, thereby ensuring the safety of the filling port.

[0005] The purpose of this utility model can be achieved by adopting the following technical solutions:

[0006] A floating inflator head device comprises a mounting seat and an adjustment mechanism, wherein the adjustment mechanisms are provided in plurality and are evenly arranged along the four sides of the mounting seat; a through hole is provided on the mounting seat for the inflator head to pass through, and a pressure rod of the adjustment mechanism extends into the through hole and presses against the outer wall of the inflator head; the diameter of the through hole is larger than the diameter of the inflator head; when the inflator head is docked with the filling port, the inflator head presses against the pressure rod of the adjustment mechanism, causing the corresponding pressure rod to extend or retract, thereby realizing self-adjustment of the position and angle of the inflator head.

[0007] As a preferred solution, a bushing mechanism for limiting the axial direction of the inflation head is sleeved in the through hole, the inflation head is sleeved in the bushing mechanism, and the pressing rod of the adjustment mechanism presses the outer wall of the bushing mechanism.

[0008] As a preferred solution, the adjustment mechanism includes a plug, a pushing rod and an elastic member. The mounting seat is surrounded by mounting holes connected to the through hole. One end of the pushing rod extends into the through hole through the mounting hole. The two ends of the elastic member respectively press the pushing rod and the plug to press the pushing rod into the through hole. The plug is installed on the mounting hole.

[0009] As a preferred solution, an annular groove is provided on the outer wall of the bushing, and the pressing rod of the adjustment mechanism extends into the annular groove.

[0010] As a preferred solution, the bushing and the inflation head are connected by a transition or interference fit.

[0011] As a preferred solution, the number of the mounting seats is multiple and they are distributed along the axial direction of the inflation head.

[0012] As a preferred solution, the elastic member is a spring.

[0013] The implementation of this utility model has the following beneficial effects:

[0014] 1. When the inflator head and the filling port are mated, if there is any misalignment between them, the inflator head will press against the adjusting mechanism's push rod, causing it to move or rotate within the through-hole, thereby automatically adjusting the inflator head to precisely mate with the filling port. During this process, no rigid collision occurs between the inflator head and the filling port, preventing damage to the filling port and protecting its safety and quality. As the inflator head presses against the push rod, a portion of the rod retracts, while the corresponding portion extends and enters the through-hole, ensuring that the push rod maintains pressure on the inflator head.

[0015] 2. Under normal conditions, the elastic member presses against the push rod, forcing one end of the push rod into the through-hole, ensuring that the push rod always remains pressed against the bushing, keeping the inflation head in a stable position. When the push rod is subjected to the outward force of the inflation head, the elastic member is compressed, and the push rod retracts into the through-hole, while the push rods in other positions extend in the direction of the push rod's movement, thereby re-stabilizing the inflation head in its new position.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] Reference Figures 1 to 3 The present embodiment relates to a floating inflation head device, comprising a mounting seat 1 and an adjustment mechanism 2, wherein the adjustment mechanism 2 is provided in plurality and is evenly arranged along the four sides of the mounting seat 1; the mounting seat 1 is provided with a through hole 11 for the inflation head 10 to pass through, and the pressing rod 21 of the adjustment mechanism 2 extends into the through hole 11 and presses the outer wall of the inflation head 10; the diameter of the through hole 11 is larger than the diameter of the inflation head 10; when the inflation head 10 is docked with the filling port, the inflation head 10 presses the pressing rod 21 of the adjustment mechanism 2, causing the corresponding pressing rod 21 to extend or retract, thereby realizing self-adjustment of the position and angle of the inflation head 10.

[0023] When the inflation head 10 is docked with the filling port, the driving device 100 drives the entire device to move toward the filling port; if there is a position deviation between the inflation head 10 and the filling port, the inflation head 10 will press the pressure rod 21 of the adjustment mechanism 2, causing the pressure rod 21 to move or rotate in the through hole 11, thereby achieving automatic adjustment of the inflation head 10 to accurately dock with the filling port. During this process, no rigid collision will occur between the inflation head 10 and the filling port, thus avoiding damage to the filling port and protecting the safety and quality of the filling port. In the process of the inflation head 10 pressing the pressure rod 21, a part of the pressure rod 21 will retract, while the corresponding other part of the rod will extend and enter the through hole 11, so that the pressure rod 21 always maintains a pressing state on the inflation head 10.

[0024] The through hole 11 is provided with a bushing mechanism 3 for limiting the axial direction of the inflation head 10. The inflation head 10 is sleeved in the bushing mechanism 3, and the pressing rod 21 of the adjusting mechanism 2 presses the outer wall of the bushing mechanism 3. The bushing mechanism 3 not only protects the inflation head 10, but also limits the axial direction of the inflation head 10. When the driving device drives the entire device to move, the mounting seat drives the inflation head to move toward the filling port through the bushing mechanism 3. There is a gap between the bushing mechanism 3 and the through hole 11, that is, the pressing rod 21 of the adjusting mechanism 2 extends into the through hole 11 and presses the outer wall of the bushing mechanism 3.

[0025] The adjusting mechanism 2 includes a plug 22, a push rod 21 and an elastic member (not shown in the figure). The mounting seat 1 is provided with mounting holes 12 connected to the through hole 11. One end of the push rod 21 extends into the through hole 11 through the mounting hole 12. The two ends of the elastic member respectively press the push rod 21 and the plug 22 to press the push rod 21 into the through hole 11. The plug 22 is installed on the mounting hole 12. The adjusting mechanism 2 can use existing spare parts, such as a plunger. Under normal conditions, the elastic member presses the push rod 21 and presses one end of the push rod 21 into the through hole 11, so that the push rod 21 always maintains a state of pressing against the bushing mechanism 3, allowing the inflation head 10 to remain in a stable position. When the pushing rod 21 is subjected to the outward force of the inflation head 10, the elastic member is compressed and the pushing rod 21 retracts into the through hole 11, while the pushing rods 21 at other positions extend along the movement direction of the pushing rod 21, so that the inflation head 10 is stabilized again in the new position.

[0026] An annular groove 31 is formed on the outer wall of the bushing mechanism 3, into which the push rod 21 of the adjustment mechanism 2 extends. As the inflation head 10 moves along the axial direction and docks with the filling port, the drive device drives the entire device to move, causing the inflation head 10 to dock with the filling port. During the entire movement of the device, the mounting base 1 drives the inflation head 10 to move via the bushing mechanism 3, and the bushing mechanism 3 and the inflation head 10 are connected by a transition fit or interference fit.

[0027] In order to make the adjustment mechanism 2 generate a relatively uniform force on the inflation head 10 in the axial direction, the mounting seat 1 is provided in multiple numbers and distributed along the axial direction of the inflation head 10. Figure 1 In the embodiment, there are two mounting seats 1 , and the two mounting seats 1 are distributed along the axial direction of the inflation head 10 .

[0028] The elastic member is a spring. Of course, the elasticity can also be made of other materials with better elasticity.

[0029] The working principle of this utility model is as follows:

[0030] Step 1: After the plastic hollow cavity is placed, the driving mechanism will drive the inflation head forward, and the inflation head will extend into the filling port of the plastic hollow cavity.

[0031] Step 2: During the forward movement, if the inflation head 10 contacts the inner wall of the filling port of the plastic hollow cavity (inaccurate docking), the inflation head 10 will press the bushing mechanism 3, causing the bushing mechanism 3 to press the pressing rod 21 in the corresponding direction, thereby changing the position and direction of the inflation head 10, so that the inflation head 10 and the filling port can be readjusted and accurately aligned.

[0032] Step 3: After the charging head 10 is docked with the filling port, a leak test is performed on the plastic hollow cavity. After the test is completed, the driving mechanism drives the charging head back to its original position. After the charging head is separated from the filling port of the plastic hollow cavity, the corresponding pressing rod 21 will extend or retract to its original position, causing the bushing mechanism 3 to move to the center of the through hole 11, thereby driving the charging head back to the center of the through hole 11 and waiting for the next cycle to begin.

[0033] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
